We will meet tomorrow at 16:00 in the CoPS groupromm (A5:1041). There 
has been a slight incapacitation of the food organizing group, but there 
will be food after the presentations! However, I need help in buying 
some drinks and snacks. I would be grateful if a few people could meet 
up with me at 11:00 tomorrow Thursday in the rotunda at the main 
entrance to go and get some of this important stuff.

... and the chance for up to three minutes of self promotion with the
newly formed Cosmology & Gravitation Working Group. Sounds tempting?
Then mark Thursday 19:th at 16:00 in your calendars. This is when we
will meet and start of by telling each other about our research
interests (very similar to the Theory WG gong show for you that attended
it) followed by food, drinks, physics brainstorming etc etc. The format
of the presentations will be three minutes (hard limit), no slides,
optional black board, no questions. A doodle will be set up soon for the
occasion so that we know how much food to order. Stay tuned!

Hello,

I propose to have the next meeting of the Cosmology & Gravity group
next week on Wednesday 3 June from 2 - 3 pm. We will be in the so-called
Aina Elvius meeting room on the astronomy floor.

We will discuss this paper on early Supermassive Black Hole growth:
http://www.nature.com/nature/journal/v518/n7540/full/nature14241.html

If you are an observer, please think critically about the observations
being presented.

If you are a theoretician, please think critically about the theoretical
implications of the claimed discovery.

All welcome,
Garrelt

Hi,

Being the most recently formed working group, we got the honour of 
arranging the very first Klein Bottle of the fall, tentatively on Oct 
7:th at 17:00. As usual, the format would be that we arrange for some 
simple food and drinks and some fun activities/presentation. Please 
think about this until we meet Sep 23:th when we should make some 
concrete plans (and distribute responsibilities).

Dear all,

The first meeting of the fall for this working group will take place on September 23th at 13:15 in A5:0019 (the CoPS grouproom).
Apart from discussing future activities for the fall, including the Klein Bottle on 7 October (!), we will also have a special guest:
Justin Alsing from  Imperial College London (where he is working under Alan Heavens and Andrew Jaffe) will present his work on
weak gravitational lensing and statistics in cosmology (in a non-technical fashion).

All welcome,

Subject: [OKC-CosmologyGravity] Notes from today's meeting
Message-ID: <56029FAC.8050807@fysik.su.se>

These are the notes from the C&GWG meeting today:

- The aim is to meet every other Wednesday at 13:15-14:15, taking turns 
between the 5th and 6th floor. The content is flexible and could include 
internal and external presentations, journal discussions, brainstorm 
sessions etc.

- Mikica Kocic and Emily Freeland graciously agreed to host these 
events, of course with help from all of us. Thank you! Please tell them 
if you have suggestions on possible group activities.

- We will host the next Klein Bottle 7th October at 17:00. We agreed to 
have it in the VLR at the Astronomy Dept. Göran Östlin will be 
responsible for drinks, Raphael Ferretti for food (with possible help 
from Ariel Goobar if smörrebröd is an option) and Rahman Amanullah for 
content. Possible activities discussed were
     1) A cosmological poll amongst selcted participants, with 
correspondning picture taken.
     2) A Physics show.
     3) A gravitational wave presentation, possibly by Stephan Rosswog.

I will let Serena know that we are on for 7th October at 17:00.

I'll let Mikica and Emily decide if and where we should meet before the 
Klein bottle in two weeks.

Best / Edvard

Hi,

since you made me in charge of the upcoming Klein Bottle, I now have a request for all of you!  I would like for each one of you to come up with a question related to your field.  The question should preferably be general enough to be of interest to everyone in the OKC, but at the same time the answer should not be obvious to everyone.  Please also provide four possible alternative answers with one being the correct one (and please let me know which one it is).  If you do not come up with a question before *this Friday*, you may expect an unimaginably cruel punishment from me.  An example of a question could be:

What is the dominating the mass of the proton?
  a) The sum of the rest masses of the quarks
  b) The sum of the rest masses of the gluons
  c) The combined binding energy
  d) Chiral symmetry breaking

The plan for the Klein Bottle is that we will start at 17.00 with drinks (organised by Göran) and mingle.

* Around 17.20 we will have a short quiz based on your questions.   However, this will not be a traditional quiz competition.  We will sample all answers simultaneously and present a statistical, collective, live, answer to each question using state of the art technology and high-perfomance computing.

* Around 17.40, Stephan Rosswog will enlighten us on the topic “Is there any chance of detecting real sources at astronomical distances with Advanced LIGO?”

* Dinner will be served around 18.00 (organised by Raphael).  During dinner Seméli (with friend(s)?) will entertain us with various examples illustrating why Hollywood directors should take some elementary physics classes.

Cheers,

  Rahman

Hi,

I now have enough questions.  Thanks for your creative efforts!   It would be great if everyone that contributed questions also could say a few words about the correct answer after it has been revealed (for example some of you wrote a short motivation/calculation to the correct answer in your email).

Cheers,

Hi all,

Our next meeting will occur on Wednesday Oct 21 at 13:00 in the CoPS 
group room A5:1041.

The topic is quasars, in the continuation of the meeting from June. 
Ariel will overview the paper on early super-massive black hole growth 
<http://www.nature.com/nature/journal/v518/n7540/full/nature14241.html>, 
and then we proceed with the discussion about the implications, both 
from the observational and the theoretical point of view.

Welcome!

Best,
Mikica

It is indeed, but we were only three present at that occasion so it 
should be worth doing again. Your input would of course be highly 
appreciated!

Hi all, we meet this Wednesday at 13.15 on the 6th floor in the
western common room.   Martin Sahlén will talk about :

Title: Cluster–Void Degeneracy Breaking: Dark Energy, Planck and the
Largest Cluster & Void

Abstract: Combining galaxy cluster and void abundances breaks the
degeneracy between mean matter density Ωm and power spectrum
normalization σ8. Consistent with Planck, we constrain Ωm and σ8 in a
flat ΛCDM universe, using extreme-value statistics on the claimed
largest cluster and void. We make a strong two-object detection of
dark energy, independent of other dark energy probes. Cluster–void
studies offer complementarity in degeneracy, scale, density, and
non-linearity – of particular interest for tests of modified gravity.

Subject: [OKC-CosmologyGravity] Extra Thursday colloquium
Message-ID: <5637433B.2070809@fysik.su.se>

Hi all,

Spephan Rosswog asked me to alert you all that there will be an extra 
colloquium Thursday at 14:00 that should be of special interest to us:

Radio astronomy and the centenary of general relativity
           AlbaNova and Nordita Colloquium

     Speaker :     Michael Kramer (Max-Planck Institute for Radio 
Astronomy, Bonn)

     Abstract :     This year, we celebrate the centenary of Einstein’s 
theory of general relativity. When the theory was conceived, the number 
of experimental tests to confront the theory with was limited. Since 
then we have come a long way. In particular astronomical observations 
provide precision tests that were inconceivable even 50 years ago. We 
use neutron stars observable as pulsars to provide the most precise 
tests for strongly self-gravitating bodies, to prove that gravitational 
waves exist or to measure the effects of curvature of space time. We 
also attempt to determine the properties of black holes, such as their 
mass and spin to test the description of black holes within general 
relativity. One of the highlights will be an image of the “shadow" of 
the supermassive black hole in the centre of our Milky Way. Soon we also 
expect that the direct detection of gravitational waves opens up a new 
window to Einstein’s Universe. In all cases, neutron stars or black 
holes play a crucial role. In this talk I will review some of the 
current and future tests of general relativity, but will also mention 
alternative theories of gravity and other applications of radio 
astronomy for fundamental physics, such as studying the 
equation-of-state of super-dense matter.

Subject: [OKC-CosmologyGravity] IGM at high redshifts,
	Wed Nov 18 at 13:15 in A5:1041
Message-ID: <56472C14.2060409@fysik.su.se>

Dear all,

The next meeting of the Cosmology & Gravity group is scheduled on 
Wednesday Nov 18 at 13:15 in the CoPS group room A5:1041.

The proposal is to discuss the limits on intergalactic dust during 
reionization in the view of http://arxiv.org/abs/1510.07047 where Imara 
& Loeb constrain the dust-to-gas ratio in the IGM at high redshifts.

For the benefits of a wider audience of group members, the suggestion is 
to begin with the short non-technical introduction to the subject which 
would then transit into a more technical discussion. (For this ~10 min 
intro we need a volunteer! Anyone??)

All welcome,
Mikica

Dear All,

Today at 13.15 we will have our Marit Sandstad talking about recent work (by her, Cornelius Rampf (ICG Portsmouth), and myself) on primordial black holes (see: http://arxiv.org/abs/1512.00488 ):

Title:
Effects of Critical Collapse on Primordial Black-Hole Mass Spectra

Abstract:
Particularities of the early-Universe physics — such as bumpy features in the inflationary power spectrum or phase transition — may lead to the production of primordial black holes. If the primordial black holes are sufficiently large, they can provide a dark-matter candidate, otherwise the effects of their evaporation can have very large observational signatures. Hence comparison between predictions and observational bounds for primordial black holes are of great interest in cosmology. Primordial black holes are generally thought to form when density perturbations that exceed a threshold value re-enter the horizon and collapse into a black hole. In a first approximation this is assumed to result in primordial black holes of horizon mass M_H. However, it has been known since the late nineties that the collapse obeys a critical scaling, M = k M_H ( delta - delta_c )^gamma, where delta and delta_c are the density contrast and its threshold value, respectively, and k and gamma are constants. The effects of this scaling has been considered negligible or degenerate with other effects in the literature. In this talk I will show the results of our recent re-analysis in the context of several models of primordial black-hole formation. Comparing these results to the current status of observational bounds, we argue that the critical collapse should be taken properly into account in any comparison of a particular model to observations.


See you there!

Florian



P.S.: As usual, there will be coffee afterwards.
